## Vehicle Code Readers
### Basic vs. Advanced Readers
Entry-level tools provide fault codes like **P0171** or **C1234**, requiring manual interpretation. Advanced systems like the BlueDriver Pro offer dynamic metrics including:
– Coolant heat levels
– Fuel trim values
—
## DTC Format Breakdown
Vehicle-specific fault markers follows this pattern:
1. **System Identifier**:
– **P** = Powertrain
– **C** = Undercarriage
2. **Manufacturer Specification**:
– **0** = Universal definition
– **1** = Manufacturer-specific
3. **Functional Area**:
– **3** = Spark components
—
## Diagnostic Process Steps
1. **Symptom Verification**:
– Driving simulation to verify symptoms
2. **Code Retrieval**:
– Connect diagnostic tool to DLC connector
3. **Snapshot Data Review**:
– Examine vehicle vitals at error occurrence
4. **Component Testing**:
– Circuit analysis on sensors
